Struct RefsArray

pub struct RefsArray<const N: usize, V>(/* private fields */)
where
    V: Variant;

A constant number of references.

Implementations

impl<const N: usize, V: Variant> RefsArray<N, V>

pub fn as_slice(&self) -> &[Option<NodePtr<V>>]

Returns the node pointers as a slice.

pub fn get(&self, ref_idx: usize) -> Option<&NodePtr<V>>

Returns the node pointer at the ref_idx position of the references array.

pub fn set(&mut self, ref_idx: usize, node_idx: Option<NodePtr<V>>)

Sets the the node pointer at the ref_idx position of the references array to the given node_idx.

pub fn set_some(&mut self, ref_idx: usize, node_idx: NodePtr<V>)

Sets the the node pointer at the ref_idx position of the references array to the given node_idx.

pub fn set_none(&mut self, ref_idx: usize)

Un-sets the the node pointer at the ref_idx position of the references array.
